WILLIAM R. SANFORD, OF BROOKLYN, NEW YORK.

ADVERTISING-SIGN.

SPECIFICATION forming part of Letters Patent No. 473,239, dated April 19, 1892.

Application filed October 7, 1891.

T0 at whom it may concern:

Be itknown that I, WILLIAM R. SANFORD, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and-useful Improvement in Advertising-Signs, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an advertising-sign to be placed in elevated railway-cars, streetcars, and other vehicles and places, and the principal feature of which consists of an endless curtain upon which reading or pictorial advertising matter is printed or otherwise inscribed or delineated and which rolls over rollers placed horizontally inside of a frame.

My invention consists in the means hereinafter described and claimed through which the rolling of the curtain to present to view in regular succession different parts of the advertising matter is produced by the movement of the car or other vehicle or body in whichthe sign is placed.

Figure 1 in the drawings represents a front View of a sign embodying my invention, having a part of the advertising-curtain removed to show the operating mechanism to View. Fig. 2 represents a transverse vertical section in the line :0 cc of Fig. 1.

Similar letters of reference designate corresponding parts in both figures.

A designates a frame, in or on the upright ends of which are the bearings for two parallel horizontal rollers O O. B is the endless curtain running upon said rollers.

D is a support (represented in the form of abracket) secured to one of the upright sides of the frame A and projecting directly between the rollers within the curtain B,between the front and back runs thereof. From the end of this bracket D is suspended a pendulum F, and between the said pendulum and the upright sides of the frame to which the said bracket is secured a bearing is provided in said bracket for a shaft N, on which are firmly secured a ratchet-wheel E and a pulley K. From the pulley K a band L runs around the lower roller 0, a groove being provided in the said roller for the band to run in without interfering with the portion of the curtain which is on the said roller. The pulley K Serial No. 408.045. (No model.)

being at right angles and havingit axis at right angles to the axis of the rollers, the band L cannot interfere with any other portion of the curtain.

H is a lever having its fulcrum in the bracket or support D and carrying at its upper end a pawl I, engaging with the ratchet-wheel E, and being connected at its lower end by a rod G with the pendulum F. The fulcrum of the lever H in the example represented is the shaft N, the lever being fitted to the said shaft to swing independently of the latter.

J is a stop-pawl for preventing the ratchetwheel and pulley from turning in the opposite direction to that in which the pawl I is intended to turn in.

By the movement of the car or other vehicle or body in which the frame A and its contained sign are placed a swinging motion is given to the pendulum, and by that means motion is given through the rod G and lever H to the pawl I, which is thus caused to turn the ratchet-wheel and pawl slowly, and thereby turn the lower roller O, which moves the curtain. The actuating mechanism being all within the curtain, it is thereby concealed from view, and, moreover, occupies no extra space within the frame. Hence the apparatus is brought within the smallest possible dimensions.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with an endless curtain and two rollers for carrying the same and a frame for supporting said rollers, of a bracket attached to said frame and projecting therefrom directly between said rollers, a pulley and attached ratchet-wheel and a pendulum carried by said bracket, a pawl actuated by said pendulum and engaging with the ratchetwheel, and a band between the said pulley and one of the rollers, said bracket, pulley, ratchet-wheel, pendulum, pawl, and band being within the curtain, between the front and back runs thereof, substantially as herein set forth.

WM. R. SANFORD.
